CLINICAL AND REGULATORY
FDA granted full approval for Elahere for certain ovarian cancer patients
Patients with these cancers often present with late-stage disease, undergo surgery and are then treated with platinum-based chemotherapy. They may become resistant to this treatment and require another therapy, such as Elahere. Elahere was first granted FDA accelerated approval in November 2022 and the conversion to full approval is based on data from the confirmatory Phase 3 MIRASOL trial. This trial compared Elahere to investigator's choice of chemotherapy in patients with platinum-resistant ovarian cancer whose tumors express high levels of FRα and who have been treated with up to three prior therapies.
Enhertu demonstrated survival benefit in ultralow HER2 population
Positive high-level results from the DESTINY-Breast06 Phase 3 showed that Enhertu (trastuzumab deruxtecan) demonstrated a statistically significant and clinically meaningful improvement in PFS compared to standard-of-care chemotherapy in the primary trial population of patients with HR-positive, HER2-low (IHC 1+ or 2+/ISH-) metastatic breast cancer following one or more lines of endocrine therapy. A statistically significant and clinically meaningful improvement in PFS was also observed in the overall trial population (patients with HER2-low and HER2-ultralow [defined as IHC 0 with membrane staining; IHC >0<1+] metastatic breast cancer). A prespecified subgroup analysis showed the clinically meaningful improvement was consistent between patients with HER2-low and HER2-ultralow expression.
